That's actually a Brymen meter, just private labeled and in a different color plastic housing. Amprobe and Fluke are sister divisions. Sort of "value" and "premium" but frankly a lot of Amprobe (Brymen) meters are much nicer than Fluke. They use Fluke Labs for quality control. The probes are OK, nothing top of the line but get the job done. I've damaged a couple over time but I use my meter every day a lot since I do a lot of troubleshooting, LOTO in industrial plants, and other things where the meter is always in my "EDC" (every day carry) bag, right beside the Klein branded Megger. Like any South Korean company if there's another little feature they can add for under $1, they will.
As far as holding up, I'm not sure exactly how to describe this but they break at the point where you drop them or do something destructive to them, roughly about the same point where the Flukes fail. So really it's not a bad meter at all in my opinion or I'd quit buying them. Still really like my 54NAV but I'm using it for heavy industrial work and our crew is heavy into high end technical work.
Personally though I've been eyeing up others. First is this one:

I have clamps. Scratch that...I have some ridiculous clamps. And Rogowski's. I carry a PdMA with 3000 A Rogowski's if you know what that is. Rogowski coils by the way are nothing like iron core clamp-on meters. They can easily go around most anything, and they are basically immune to the problem of the conductors not being centered and if they are off-angle (tilted) a bit, they are still pretty accurate. They also work at pretty much any frequency. The one thing they won't do is that they can't measure DC. That's where those Brymen meters that do DC have a Hall Effect sensor in the base of the iron core arms. Here's another one that looks promising but we actually have Kleins around the shop so I know that they hold up pretty well.
